Optic canal duplication is a rare condition that affects both sexes, people of all ages, and people of different races. The purpose of this study was to determine the prevalence of optic canal duplication and to investigate its clinical and developmental implications. Methods: For the study, 100 dry human skulls of both sexes and ages were used. These skulls were examined grossly and morphologically to determine if the optic canals were duplicated. Additional optic canals were discovered in three skulls (3 percent cases). Only two (2%) of the cases (2%) had bilateral duplication, while one (1%) had unilateral duplication. The larger main canal was in its usual position, directed posteromedially upwards, and joined the anterolateral end of Sulcus chiasmaticus. In the lesser wing of the sphenoid, the smaller or duplicated canal was inferolateral to the main canal. Bony septa separated the main and accessory canals. Conclusion: Understanding additional optic canals is critical when performing surgical exploration of optic canals during tumor removal, decompression of optic canals, or surgical access to the cavernous sinus or Sella turcica.
